Title:

HIGH-PERFORMANCE SIMULATED MOVING BED DEVICE AND HIGH-PERFORMANCE SIMULATED MOVING BED TECHNIQUE

Document Type and Number:

WIPO Patent Application WO/2020/098295

Kind Code:

A1

Abstract:

Disclosed are a high-performance simulated moving bed device and a high-performance simulated moving bed technique. The high-performance simulated moving bed device comprises an adsorbent bed, a raw material feeding system, a desorbent feeding system, a circulation system, a liquid extract system, a liquid raffinate system, a program-controlled valve assembly, and an automatic control system. The invention employs the program-controlled valve assembly, instead of a conventional multi-channel rotary valve, to control cycle switching of the simulated moving bed, thereby reducing manufacturing costs of the device. In the invention, each pipeline connected to an adsorption column has the same volume, and the relative position of a circulation pump in an operation region does not change, such that the circulation pump has a constant flow rate to allow small pressure fluctuations and easy control.
